Growing Peppers Indoors – Guidelines & Tips

Peppers are one of the most popular vegetables grown in home gardens, and growing them indoors can be just as satisfying. Nothing beats the taste of freshly-harvested peppers from your own indoor garden, and now you have no seasonal obstacles. There are a few steps to follow, but the effort is worth it.

Maintenance & Requirements

Peppers have specific temperature, light, and humidity requirements that must be met to ensure success. Temperatures over 70-75 degrees F and below 55-60 degrees F can be detrimental to pepper growth and fruit production. Indoors, one of the best choices is an 80-85 degree F temperature range.

Light is an important factor for pepper growth. Depending on the amount of natural sunlight available in your home, you may need to supplement with artificial lighting. Natural sunlight is best, so consider windows or mirrors that will direct the sun’s rays to the peppers.

Humidity is another critical factor. If you are having a difficult time maintaining/increasing humidity levels, consider using an artificial humidifier. Keep the humidity level between 65-75% and this should help keep the peppers healthy.

Soil & Fertilizing

Use a potting soil specifically designed for peppers or other vegetables, as this will give the peppers the nutrients they need to thrive. The pH of the soil should also be maintained, as acidic or alkaline soil can affect pepper growth.

Additionally, fertilizing is an important step. Fertilizers can help increase the growth, yield, and quality of the peppers. Apply fertilizer when you plant the peppers, as well as after each harvest. Be sure to read the directions for your specific fertilizer and follow the instructions closely.

Watering & Pollination

Water is an important factor for pepper growth. The soil should remain evenly moist, but avoid over-watering. Soil should be dry to the touch between waterings.

Peppers are self-pollinating and don’t need help to produce fruit, but they do benefit from some extra TLC. Further encourage pollination by lightly shaking the pepper plants to ensure the pollen is distributed.


Harvest peppers when they are firm and have reached their mature color (red, yellow, or green). Cut the peppers with scissors or a knife to avoid causing damage to the plants.


With the right conditions, growing peppers indoors can be a rewarding experience. By following the guidelines and tips outlined above, you should be able to successfully grow peppers in your home. Enjoy the fresh flavor of your harvested peppers, and don’t forget to share them with friends!
